• Before installing the wiring, switch off the power supply to the air conditioning system and centralised ON/OFF controller. Installing the
wiring while the centralised ON/OFF controller power supply is switched on may cause the centralised ON/OFF controller to malfunc-
tion.
• Check to ensure that the wiring is correct. Incorrect wiring may cause malfunction of the centralised ON/OFF controller.
• DO NOT run all the transmission cable for the centralised ON/OFF controller along the power line and other transmission cables, or
malfunction may occur due to the noise, etc. If the transmission cable for the centralised ON/OFF controller is required to be run along
the power line and other transmission cables, separate the cable more than 30 cm away from other cables, or run the cable through
a metal tube and earth the tube.
• In case of applying high voltage to the TB2, the fuse on the PCB is blown out. In such a case, firstly correct the wiring to TB1, and
then set Nº.2 pin ON.
• Connect the shield tube of cable to earth.
